Task 37 recently published a technical brochure on “A perspective on the potential role of biogas in smart energy grids”. Increased generation of electricity from wind and solar installations is leading to challenges in terms of balancing electricity demand with supply and managing the increasing occurrences of surplus electricity. Biogas systems can facilitate increased proportions of variable renewable electricity on the electricity grid mainly through use of two different technologies: demand driven biogas systems which increase production of electricity from biogas facilities at times of high demand for electricity, or temporary storage of biogas at times of low electricity demand; and power to gas (P2G) systems when demand for electricity is less than supply of electricity to the electricity grid, allowing conversion of surplus electricity to methane.
